lhu/enor Patented July 15, 1941 r jorsics IGNITION DEVICE FOR OIL RANOssian A. Hedengren, Taunton, Mass; assignor to Sears, Roebuck and 00.,ChicagoJIlL, a corporation of New York Application December 9, isaviseriarno. 8.91s BI'Claims. (Cl; 158-90) This invention relates to oilranges and to combination oil and gas ranges, and-is concerned moreparticularly with the ignition of oil burners.

It has heretofore been necessary to ignite oil range burner wicks-orkindlers by hand, requiring either raising-the cylinder or other shieldof the burner and applying a lighted match and then lowering the shieldor projecting the lighted end of a long rod down into the shield. Inlocalities where gas is available this inconvenience may be avoided byequipping the range with mechanism of my invention.

Further objects and advantages of my invention will appear as thedescription proceeds.

In the accompanying drawing the figure is a fragmentary elevationshowing oil burners or the like combined with automatic-igniting meansof my invention.

The burners It may be mounted on any suitable frame F-and are suppliedwith kerosene or other liquid fuel through vertical feed tubes H, thefuel being introduced tothe tubes laterally, asatl Id. The tubes llterminate at their bottoms in' carbon legs I lb,each closed by a screwcap- Hc, whereby carbonand other solids settling out of the fuelmay beremoved. The-bumers are provided with asbestos or other suitablekindlers l2 projectingfreely upward from the fuel containers or bases l3of theburners, said bases supporting perforated shields such ascylinders or drums l4 which-surround the free tips of the kindlers. Thebottoms of the shields are surrounded by flanges l5 on the bases of theburners.

Pivotally supported at other suitable part of the structure is a leverl8 having at one end a knob 19 projecting to the outside through anopening 20 in the casing 2|. Links 23 pivoted at 24 to the other arm 25of the lever have forked ends 26 in whose crotches hooks 21, attached toadjacent portions of the drums 14, are received. Now it will be observedthat the knob 19 is normally held in the position shown in full lines,as are the other parts cooperating therewith, and upon depression of theknob the drums are tilted as indicated in dotdash lines, the flanges l5preventing dislocation of the drums. When the knob is released, gravitywill return the parts to their full line positions. If desiredstructural means could be provided for this purpose.

An important feature of my invention involves the application of a flameto the kindlers while they are exposed by the tilted drums. To this enda pipe 30 from a suitable source of gas leads I! from the frame or to avalve 3| from which extends a pipe 32 which projects up between theburners and terminates in apilot 33. A small pilot flame is normallykept burninggth size of the'flame being controlled by means ofaby-passscrew 35. A-pushbutton valve stem 36 associatedwith the valve 3|is urgedoutward to closed position by a spring (not shown) in the valvebody. When the stem 36 is depressed, there. is I an increase 'intoflthe-pilot so that jetsof flame as shown at 38 are emitted and sodirected'as to strike the kindlersof theburners when unobstructed by thecylinders-l4. V 'lfudesiredlthe knob could be depressed to tilt thecylindersto-the' desired extent and then the attendant could Lpressthestem separately with his finger until the pilot'flame jetsignite the kindl'ers; whereupon'both knob and stem could be released Theknob and stemthus could be located apart or adjacent 'eachother.However, I preferlto'.providemeans whereby both actions may be effectedmerely by moving the knob l9. 'Laocordingly provide the knob with a lug40 arranged to impinge :upon the valve stem 36 before-the knob hascompleted its actuating movementand so that when such movement iscomplet'ed' the cylinders l l are adequately tilted'and the-jets'offlame directed to and ignite the adjacent kindlers' of'the burners. Thisrequires but a momentor twd and then the knob is'released 'allowi'ng theshields to be returned, the receding lug 40 permitting the stem 36 to bereturned by the valve spring to its closed position so that the smallpilot flame continues to burn, the parts being thus ready for the nextlighting operation without further ado. same result could be obtained invarious ways, as, for example, by extending the height of the stein andallowing the knob to depress it.

If desired, separate provided for each cylinder, either with a commonpilot or separate pilots. The links may be readily removed from thelever, or disconnected from the hooks 21, so that either cylinder may beelevated without the other. The mechanism is accordingly applicable to asingle burner or any desired number of burners.

Although I have illustrated burner construction of the blue flame type,it will be appreciated that my invention is applicable to burners of alltypes employing drums or equivalent shields.

I am aware that many changes may be made and numerous details ofconstruction varied through a wide range without principles of myinvention, and I therefore do not Of course, the

purpose limiting the patent granted hereon otherwise than asnecessitated by the prior art.

I claim:

1. A burner having a fuel container and a shield movably associated withsaid container, means for shifting said shield to expose said fuel,means providing a pilot gas flame in such proximity to said fuel that ajet formed from said flame will ignite said fuel, and means forprojecting said flame into the form of a jet isniting said fuel while soexposed, said flame projecting means being so arranged as to be operatedby said shifting means.

2. A plurality of burners, each having a fuel container and a shieldmovably associated therewith, means for shifting all of said shields toexpose the fuel in each container, and means operated by said shiftingmeans for simultaneously igniting the fuel in all of said containerswhile so exposed.

3. A plurality of burners, each having a fuel container and a movableshield therefor, means for shifting said shields to simultaneouslyexpose the fuel in all of said containers, means providing a gas flamepilot in such proximity to the fuel that jets formed from said flamewill ignite the fuel in all of said containers, and, means operated bysaid shifting means for projecting said flame into a plurality of jetssimultaneously igniting the fuel in all of said containers while soexposed. n

4. The combination in an oil burning stove, of a burner includingcombustion tube means arranged to be elevated for lighting the burner,means for elevating said combustion tube means including a manuallyoperable pivotally mounted lever, and a flame projecting gas lighterdirected toward said burner including a control, valve arranged to beactuated by said lever for oper-e: atlng the lighter as an incident tomovement of said lever for elevating said combustion tube means.

5. The combination in an oil burning range or the like, of a burnerincluding a vaporizing bowl having an open top recess therein adapted tocontain a supply of combustible fuel and sur-, rounded by an upstandingannular flange, a combustion tube assembly removably positioned on saidbowl over said recess and within said flange, an operating lever pivotedintermediate its ends, and means including a link pivotally connected toone end portion of said lever and to a side wall portion of saidcombustion tube assembly for tilting the latter about an edge portion ofsaid flange without disengaging the same in response to movement of saidoperating lever to thereby expose a portion of said recess for ignitionof the fuel therein.

6. The combination in an oil burning stove, of burners includingcombustion tube means arranged to be elevated for lighting said burners,means including a manually operable element for elevating saidcombustion tube means simultaneously, and igniting means applicablesimultaneously to said burners and including a control member arrangedto be actuated by said element for operating said igniting means toignite said burners simultaneously as an incident to movement of saidelement for elevating said combustion tube means.

7. The combination in an oil burning stove, of a burner includingcombustion tube means arranged to be levated for lighting said burner,means including a manually operable element for elevating saidcombustion tube means, and igniting means applicable to said burner andincluding a control member arranged to be actuated by said element foroperating said igniting means to ignite said burner as an incident tomovement of said element for elevating said combustion tube means, saidigniting means when operated being positioned in operative relation tosaid burner so that the movement of said manually operated element toelevate said combustion tube will be effective to ignite said burner.
